Juggle Dream Superglass Grind Diabolo Handsticks

I've been disappointed with plastic sticks that came with my beginner diabolo and snapped under moderate use, metal sticks that bent after time, and wooden sticks that just feel a little basic. These superglass sticks are nice and stiff, haven't bent after a couple of years' use, have yet to scratch or break, although they are starting to show some marks from occasional collisions.
The only downside is the foam, which is very easy to damage. If you accidentally wind the string around the foam while it's in your prop bag, you'll indelibly crease it. After a few months, you'll notice the foam gradually slipping its way down the stick, until a centimeter or so sticks off the end, which starts to rub and tear. Will buy again (but would love to be able to get replacement foam).

Been using these for a few months and they've held up really well. My eldest is a beast and regularly does 30'-40' throws and catches with a Big Top, not the lightest diabolo out there. I'm definitely going for carbon next but these things have been fabulous for learning. One thing with glassfibre is the noise they make when they hit each other sounds terminal. Never even a mark though.

We bought the diablo sticks for a triple bearing diablo in good faith, however, the sticks DO NOT hold a triple bearing diablo, and therefore break all he time! They are useless and we wouldn't recommend!

*Reply from Firetoys - we have tested these sticks ourselves and have been unable to replicate this problem. We're not hearing other reports of this problem and we are satisfied that this was an isolated incident. Though we are dissapointed to hear of this we welcome any feedback.

They break proper easy but are good in some ways
